|
00:00:02,850 --> 00:00:07,750 |
|
محمد سيد المرسلين وعلى أليه وصحبيه أجمعين محاضرتنا |
|
|
|
3 |
|
00:00:07,750 --> 00:00:12,890 |
|
اليوم السابعة في مساقى ال bio mechanics and |
|
|
|
4 |
|
00:00:12,890 --> 00:00:17,590 |
|
kinesiology هنتكلم فيها عن ال bio mechanics of |
|
|
|
5 |
|
00:00:17,590 --> 00:00:19,930 |
|
tendon and ligament |
|
|
|
6 |
|
00:00:22,970 --> 00:00:27,530 |
|
طبعا ال tendon وال ligament هي من ال connective |
|
|
|
7 |
|
00:00:27,530 --> 00:00:35,130 |
|
tissues في الجسم اللى بتعمل على ربط ال bones ب .. |
|
|
|
8 |
|
00:00:35,130 --> 00:00:38,370 |
|
يا اما two bones في بعض في ال joints اللى زى ال |
|
|
|
9 |
|
00:00:38,370 --> 00:00:43,650 |
|
ligamentأو ال .. ال bone with the muscle زي ال |
|
|
|
10 |
|
00:00:43,650 --> 00:00:47,930 |
|
tendon طبعا هم لهم تقريبا نفس الخواص بس بتختلف في |
|
|
|
11 |
|
00:00:47,930 --> 00:00:51,590 |
|
كميات ال .. ال collagen و ال .. و ال elastin لكن |
|
|
|
12 |
|
00:00:51,590 --> 00:00:56,430 |
|
هم بيحملوا نفس الخواص و هم نوع من أنواع ال dense |
|
|
|
13 |
|
00:00:56,430 --> 00:01:03,090 |
|
connective tissue طبعا التنين موجودين around the |
|
|
|
14 |
|
00:01:03,090 --> 00:01:06,850 |
|
joints of the bodyسواء كان ال ligament or tendon |
|
|
|
15 |
|
00:01:06,850 --> 00:01:11,130 |
|
لأنه لازم ال ligament هو عبارة عن الأربطة أما ال |
|
|
|
16 |
|
00:01:11,130 --> 00:01:15,530 |
|
tendons هي الأوتار و كلهم بيمروا من خلال المفاصل |
|
|
|
17 |
|
00:01:15,530 --> 00:01:19,810 |
|
لأنهالـ ligaments هي وظيفتها أنها تربط العظام مع |
|
|
|
18 |
|
00:01:19,810 --> 00:01:26,310 |
|
بعضها في العظام المفصل الواحد وأما ال tendons فهي |
|
|
|
19 |
|
00:01:26,310 --> 00:01:30,710 |
|
اللي بدها تقوم بالحركة بحركة هذه المفاصل عن طريق |
|
|
|
20 |
|
00:01:30,710 --> 00:01:38,230 |
|
الشد اللي بتعمله على ال bone يبقى both located in |
|
|
|
21 |
|
00:01:38,230 --> 00:01:41,410 |
|
and around the joints of the body and as a result |
|
|
|
22 |
|
00:01:41,410 --> 00:01:45,730 |
|
they both subjected to largedistractive or tensile |
|
|
|
23 |
|
00:01:45,730 --> 00:01:50,450 |
|
loads لأنه عمليات الشد اللي بتكون حاصلة على ال .. |
|
|
|
24 |
|
00:01:50,450 --> 00:01:55,430 |
|
التنين سواء دروس المفصل أو خارج المفصل عشان يقوم |
|
|
|
25 |
|
00:01:55,430 --> 00:02:00,330 |
|
المفصل بالحركات these are the structures that are |
|
|
|
26 |
|
00:02:00,330 --> 00:02:04,370 |
|
largely responsiblefor providing joint stability |
|
|
|
27 |
|
00:02:04,370 --> 00:02:07,570 |
|
during movement and function طبعا ال joint |
|
|
|
28 |
|
00:02:07,570 --> 00:02:12,030 |
|
stability هذه اشي كتير fundamental حتى الحركة تكون |
|
|
|
29 |
|
00:02:12,030 --> 00:02:16,550 |
|
طبيعية و فيها سلاسة و فيها smoothness عساس ان احنا |
|
|
|
30 |
|
00:02:16,550 --> 00:02:21,630 |
|
لما بتحرك المفصل بيصير عملية الشد من ال ligament |
|
|
|
31 |
|
00:02:22,020 --> 00:02:26,780 |
|
بتصير في ال muscles بتنتقل من ال muscle بالي لال |
|
|
|
32 |
|
00:02:26,780 --> 00:02:33,500 |
|
tendon ال tendon بيكون مشبوك بال bone فبصير الحركة |
|
|
|
33 |
|
00:02:33,500 --> 00:02:37,180 |
|
ال tendon and ligaments are biologically active |
|
|
|
34 |
|
00:02:37,180 --> 00:02:40,590 |
|
structuresمش يعني biological active structure انهم |
|
|
|
35 |
|
00:02:40,590 --> 00:02:47,270 |
|
عندهم قدرة على ال generation يبقى هي عادة بتكون |
|
|
|
36 |
|
00:02:47,270 --> 00:02:53,650 |
|
معرضة لل injury لل aging لأي abnormal position زي |
|
|
|
37 |
|
00:02:53,650 --> 00:02:57,350 |
|
مثلا ال immobilization فبصير في alteration في ال |
|
|
|
38 |
|
00:02:57,350 --> 00:03:02,070 |
|
composition and structureبتقل أو باتزيد الخواصة |
|
|
|
39 |
|
00:03:02,070 --> 00:03:05,130 |
|
بعتمد طبعا هو الكل دايما عارفين انه احنا ال |
|
|
|
40 |
|
00:03:05,130 --> 00:03:08,470 |
|
biological active structure هادي بيصير فيها عملية |
|
|
|
41 |
|
00:03:08,470 --> 00:03:12,450 |
|
ال regeneration طبعا إعادة البناء أو بيصير فيها |
|
|
|
42 |
|
00:03:12,450 --> 00:03:18,890 |
|
طبعا عملية الهدم أيضا these |
|
|
|
43 |
|
00:03:18,890 --> 00:03:22,630 |
|
changes in الشاشة affect mechanical improperities |
|
|
|
44 |
|
00:03:22,630 --> 00:03:25,820 |
|
ofthe tendon and ligament and as well the |
|
|
|
45 |
|
00:03:25,820 --> 00:03:31,460 |
|
functioning of the joints they are associated طبعا |
|
|
|
46 |
|
00:03:31,460 --> 00:03:36,000 |
|
زي ما احنا شايفين الصورة الموضحة هذا مفصل ال knee |
|
|
|
47 |
|
00:03:36,000 --> 00:03:44,560 |
|
مفصل |
|
|
|
48 |
|
00:03:44,560 --> 00:03:51,700 |
|
ال knee زي ما احنا شايفينه فلقيتها شايفين كهنا في |
|
|
|
49 |
|
00:03:51,700 --> 00:03:56,890 |
|
عندنا ال tendonاللي مشبوك بال بتلة اللي هو tendon |
|
|
|
50 |
|
00:03:56,890 --> 00:04:00,990 |
|
of the quadriceps او tendon بتلائي وهي في عندنا |
|
|
|
51 |
|
00:04:00,990 --> 00:04:04,350 |
|
هذا ال cartilage وفي عندنا ال ligament هذه ال |
|
|
|
52 |
|
00:04:04,350 --> 00:04:11,010 |
|
lateral collateral اللي بتربط الفيمر مع ال ال |
|
|
|
53 |
|
00:04:11,010 --> 00:04:16,830 |
|
tibia and also في عندنا هذا ال media ال collateral |
|
|
|
54 |
|
00:04:16,830 --> 00:04:21,790 |
|
لجامد و lateral collateral اللي بتربط الفيمر مع |
|
|
|
55 |
|
00:04:21,790 --> 00:04:22,870 |
|
الفيبولا |
|
|
|
56 |
|
00:04:25,020 --> 00:04:32,220 |
|
هذه التغييرات في الأسلحة تأثير على أسلحة التنضج |
|
|
|
57 |
|
00:04:32,220 --> 00:04:38,420 |
|
والتنضج ستكون مفروضة من مجلس التنضج والتنضج هنا |
|
|
|
58 |
|
00:04:38,420 --> 00:04:45,860 |
|
المهم للطبال الذين يتعاملون بالطب مع تنضج وتنضج |
|
|
|
59 |
|
00:04:45,860 --> 00:04:49,980 |
|
والتنضج والتنضج هي التعرف على هذه التغييرات |
|
|
|
60 |
|
00:04:49,980 --> 00:04:51,360 |
|
التسلسلية وميكانيكالية |
|
|
|
61 |
|
00:04:53,790 --> 00:04:57,490 |
|
saw that treatments selected will stimulate |
|
|
|
62 |
|
00:04:57,490 --> 00:05:02,110 |
|
positive tissue adaptation and improve joint and |
|
|
|
63 |
|
00:05:02,110 --> 00:05:06,890 |
|
overall function هذا الكلام يعني انه كاحنا ك |
|
|
|
64 |
|
00:05:06,890 --> 00:05:12,990 |
|
clinicians كفيزيو تيرابيس او دكتور او يعني اي حد |
|
|
|
65 |
|
00:05:12,990 --> 00:05:18,510 |
|
بيشتغل في مجال ال movement لازم يكون في عنده معرفة |
|
|
|
66 |
|
00:05:18,510 --> 00:05:21,750 |
|
حقيقية في ال mechanical properties تبع ال tendon |
|
|
|
67 |
|
00:05:21,750 --> 00:05:26,360 |
|
and ligamentهو كل ال interventions اللي بتعملها |
|
|
|
68 |
|
00:05:26,360 --> 00:05:30,640 |
|
سواء كانت ال exercise بيكون هدفها انها تحسن ال |
|
|
|
69 |
|
00:05:30,640 --> 00:05:35,600 |
|
movement و احنا عارفين انه اي limitation في ال .. |
|
|
|
70 |
|
00:05:35,600 --> 00:05:39,000 |
|
او contracture في ال tendon او الليجامنت هتعمل |
|
|
|
71 |
|
00:05:39,000 --> 00:05:44,040 |
|
انها limitation في ال movement طبعا ال structure |
|
|
|
72 |
|
00:05:44,040 --> 00:05:47,720 |
|
of the connective tissue ال tendon and ligament |
|
|
|
73 |
|
00:05:47,720 --> 00:05:52,440 |
|
compose of the connective tissue و طبعا هيمن أنواع |
|
|
|
74 |
|
00:05:52,440 --> 00:05:57,020 |
|
الـ connective tissue of the body وظيفتها انها ت |
|
|
|
75 |
|
00:05:57,020 --> 00:06:02,080 |
|
provide and maintain شكل ال body طبعا عارفين هي |
|
|
|
76 |
|
00:06:02,080 --> 00:06:06,540 |
|
supportive طبعا ال tissue و بتعمل و بتكون ال |
|
|
|
77 |
|
00:06:06,540 --> 00:06:10,180 |
|
function تبعتها mechanical بتعمل connection and |
|
|
|
78 |
|
00:06:10,180 --> 00:06:15,320 |
|
bind لسل و organs together و بتعطيني support ل ال |
|
|
|
79 |
|
00:06:15,320 --> 00:06:18,260 |
|
body يعني هي كمان بتعطي protection و بتعطي support |
|
|
|
80 |
|
00:06:18,260 --> 00:06:22,910 |
|
و بتعطي bonding كمان لالتي تجمع جميع عضلاتنا |
|
|
|
81 |
|
00:06:22,910 --> 00:06:25,570 |
|
وعضلاتنا وعضلاتنا وعضلاتنا وعضلاتنا وعضلاتنا |
|
|

00:06:25,570 --> 00:06:29,210 |
|
وعضلاتنا وعضلاتنا وعضلاتنا وعضلاتنا وعضلاتنا |
|

وعضلاتنا وعضلاتنا وعضلاتنا |
|
|
|
87 |
|
00:06:48,730 --> 00:06:52,270 |
|
الـ connective tissue proper لمنها الـ loose and |
|
|
|
88 |
|
00:06:52,270 --> 00:06:58,270 |
|
dense connective tissue طبعا الـ loose connective |
|
|
|
89 |
|
00:06:58,270 --> 00:07:01,050 |
|
tissue بنلاقيها وان موجودة في ال muscle sheets |
|
|
|
90 |
|
00:07:01,050 --> 00:07:05,930 |
|
لأنه احنا عارفين ان العضلة محاطة بالأغشية زي |
|
|
|
91 |
|
00:07:05,930 --> 00:07:08,370 |
|
الابيميزيوم و البريميزيوم و الاندوميزيوم |
|
|
|
92 |
|
00:07:08,370 --> 00:07:13,090 |
|
supporting ال epithelial tissue and encircle neuro |
|
|
|
93 |
|
00:07:13,500 --> 00:07:17,580 |
|
vascular bundles في طبعا في ان انتوا عارفين ان |
|
|
|
94 |
|
00:07:17,580 --> 00:07:24,220 |
|
العضلات بيبت .. يعني بتيجي لها ال nutrition عن |
|
|
|
95 |
|
00:07:24,220 --> 00:07:27,760 |
|
طريق ال vascularization وكمان بيجي ال nervous |
|
|
|
96 |
|
00:07:27,760 --> 00:07:30,340 |
|
system في connection مع ال nervous system فهذه |
|
|
|
97 |
|
00:07:30,340 --> 00:07:35,520 |
|
بتبقى عملية ال tube اللي بتيجي بتمر من خلالها ال |
|
|
|
98 |
|
00:07:35,520 --> 00:07:41,280 |
|
bundles of ال vascularization and nervous system |
|
|
|
99 |
|
00:07:42,530 --> 00:07:46,990 |
|
Lose connective tissue is very delicate and not |
|
|
|
100 |
|
00:07:46,990 --> 00:07:51,630 |
|
very resistant to stress and strain or strain لأن |
|
|
|
101 |
|
00:07:51,630 --> 00:07:57,630 |
|
هي loose فكمية ال fibers و ال cells فيها قليلة و |
|
|
|
102 |
|
00:07:57,630 --> 00:08:02,090 |
|
كمية ال matrix بتكون فيها كتيرة ليش بتكون خفيفة |
|
|
|
103 |
|
00:08:02,090 --> 00:08:07,010 |
|
يعني هي كده عاملة زي الجيلاتين بدنا نفهم شغلة أن |
|
|
|
104 |
|
00:08:07,010 --> 00:08:09,700 |
|
ال lose connective tissue كميةالـ fibers و ال |
|
|
|
105 |
|
00:08:09,700 --> 00:08:14,860 |
|
cells فيها قليلة و ال .. و ال matrix بتكون فيها ال |
|
|
|
106 |
|
00:08:14,860 --> 00:08:19,060 |
|
extra cellular matrix بتكون فيها كتيرة طبعا هنا |
|
|
|
107 |
|
00:08:19,060 --> 00:08:26,160 |
|
بعض ال .. ال connective tissues اللي موجودة |
|
|
|
108 |
|
00:08:26,160 --> 00:08:30,420 |
|
ال dense طبعا هنا بحتختلف بحتصر كمية ال fibers |
|
|
|
109 |
|
00:08:30,420 --> 00:08:33,760 |
|
كتيرة و كمية ال cells كتيرة و كمية ال ground |
|
|
|
110 |
|
00:08:33,760 --> 00:08:38,590 |
|
substance أقلفهي عشان كده بتكون أقل flexibility |
|
|
|
111 |
|
00:08:39,480 --> 00:08:42,960 |
|
وبتكون مقاومة لل stress لإنه لازم يكون في عندها |
|
|
|
112 |
|
00:08:42,960 --> 00:08:46,000 |
|
قدرة على التعامل لإنه مش معقول كل ما يصير pull من |
|
|
|
113 |
|
00:08:46,000 --> 00:08:51,440 |
|
ال muscles على ال bone يصير في عندنا قطع لأ احنا |
|
|
|
114 |
|
00:08:51,440 --> 00:08:55,240 |
|
بدنا تنضن أوي عشان يقدر يتحمل ال stresses اللي |
|
|
|
115 |
|
00:08:55,240 --> 00:08:58,860 |
|
بدها تكون عليه وكمان المفاصل ال .. ال arbita طبعة |
|
|
|
116 |
|
00:08:58,860 --> 00:09:04,720 |
|
المفاصل لازم تكون أوية حتى تساعد على الحفاظ على |
|
|
|
117 |
|
00:09:04,720 --> 00:09:09,680 |
|
stability of the shrineDermis of the skin is |
|
|
|
118 |
|
00:09:09,680 --> 00:09:13,160 |
|
classified as dense irregular connective tissue |
|
|
|
119 |
|
00:09:13,160 --> 00:09:16,780 |
|
لأن ال fibers و ال bundles الموجودة فيه |
|
|
|
120 |
|
00:09:16,780 --> 00:09:20,720 |
|
disorganized و مافيش عندها orientation معين فيها |
|
|
|
121 |
|
00:09:20,720 --> 00:09:24,720 |
|
أما ال tendon و ال ligament فهي classified as |
|
|
|
122 |
|
00:09:24,720 --> 00:09:27,860 |
|
dense and regular irregular connective tissue لأن |
|
|
|
123 |
|
00:09:27,860 --> 00:09:31,780 |

هي عبارة عن fibers أو bundles of fibers فهذه ال |
|
|
|
124 |
|
00:09:31,780 --> 00:09:34,700 |
|
orientation دائما بتكون ال bundles of fibers هذه |
|
|
|
125 |
|
00:09:35,010 --> 00:09:38,390 |
|
الـ ligament و الـ tendon oriented parallel to |
|
|
|
126 |
|
00:09:38,390 --> 00:09:42,830 |
|
each other يعني هذه اللي بتعطيها المتانة والصلابة |
|
|
|
127 |
|
00:09:42,830 --> 00:09:47,210 |
|
أو اللي بتساعد على ال stability this arrangement |
|
|
|
128 |
|
00:09:47,210 --> 00:09:50,890 |
|
make them particularly well adapted to resisting |
|
|
|
129 |
|
00:09:50,890 --> 00:09:55,550 |
|
the traction and tensile force لإن هم على طول |
|
|
|
130 |
|
00:09:55,550 --> 00:09:59,810 |
|
بيبقوا معرضين لعملية ال pull أو ال traction أو ال |
|
|
|
131 |
|
00:09:59,810 --> 00:10:03,650 |
|
tension forcesالـ composition of tendons and |
|
|
|
132 |
|
00:10:03,650 --> 00:10:08,410 |
|
ligaments طبعا هي زي أي dense connective tissue ال |
|
|
|
133 |
|
00:10:08,410 --> 00:10:11,870 |
|
tendons and ligaments composed of two major |
|
|
|
134 |
|
00:10:11,870 --> 00:10:16,790 |
|
compartment الcell و ال extracellular matrix يعني |
|
|
|
135 |
|
00:10:16,790 --> 00:10:19,790 |
|
هو احنا قولنا ال connective tissue زي كأنها عاملة |
|
|
|
136 |
|
00:10:19,790 --> 00:10:25,870 |
|
زي cocktail أو خليطالـ cell نفسها الـ primary cell |
|
|
|
137 |
|
00:10:25,870 --> 00:10:29,170 |
|
type in the tendon and ligament هي الفيبروسايت |
|
|
|
138 |
|
00:10:29,170 --> 00:10:32,870 |
|
الفيبروسايت هي عبارة عن mature cell لما بتكلم عن |
|
|
|
139 |
|
00:10:32,870 --> 00:10:36,850 |
|
فيبروسايت هي mature cell called fibroblast لما |
|
|
|
140 |
|
00:10:36,850 --> 00:10:40,850 |
|
بتكون immature بتكون fibroblast when it is |
|
|
|
141 |
|
00:10:40,850 --> 00:10:44,790 |
|
actively manufacturing protein الفيبروسايت هي الـ |
|
|
|
142 |
|
00:10:44,790 --> 00:10:53,500 |
|
fibroblast هي خلايا البناء في ال .. في هذا النوعفي |
|
|
|
143 |
|
00:10:53,500 --> 00:10:58,780 |
|
هذا الـtype من الـcells الـcells make up only 20% |
|
|
|
144 |
|
00:10:58,780 --> 00:11:02,440 |
|
of the total tissue volume الـfibrostatic blast هي |
|
|
|
145 |
|
00:11:02,440 --> 00:11:05,900 |
|
الـmanufactures هي خلايا البناء وبتعمل secretion |
|
|
|
146 |
|
00:11:05,900 --> 00:11:09,800 |
|
للـextracellular matrix طب إيش هي الـextracellular |
|
|
|
147 |
|
00:11:09,800 --> 00:11:14,080 |
|
matrix؟ هي عبارة عن الجيلاتين أو المادة اللي بتربط |
|
|
|
148 |
|
00:11:14,080 --> 00:11:19,560 |
|
ال fibers مع بعضها فmake up |

|
|
157 |
|
00:11:45,360 --> 00:11:50,580 |

ال .. ال mattress أو النسيج اللي .. اللي موجود هي |
|
|
|
158 |
|
00:11:50,580 --> 00:11:54,440 |
|
عبارة عن gelatinous material that fills the space |
|
|
|
159 |
|
00:11:54,440 --> 00:12:01,140 |
|
between cell and fibers طبعا هنا يعني الخلايا |
|
|
|
160 |
|
00:12:01,140 --> 00:12:05,100 |
|
الدعمة أو الرابطة هذه هي اللي بتربط ال extra cell |
|
|
|
161 |
|
00:12:05,100 --> 00:12:10,040 |
|
هي اللي بتربط ال fibersمع بعضها و ال cells مع ال |

162 |
|
00:12:10,040 --> 00:12:14,560 |

fibers it is composed of non-collagenous |
|
|
|
163 |
|
00:12:14,560 --> 00:12:18,420 |
|
structures زي ال glycoproteins و ال proteoglycan و |
|
|
|
164 |
|
00:12:18,420 --> 00:12:25,240 |
|
كمان ال water و هذا تقريبا قداش فيه ان نسب ل ال |
|
|
|
165 |
|
00:12:25,240 --> 00:12:30,020 |
|
water و ال collagen و ال elastin و ال proteoglycan |
|

اللي موجودة في ال collateral ال normal media ال |
|
|
|
167 |
|
00:12:34,340 --> 00:12:39,050 |
|
collateral ligamentsطب ال fibers هي عبارة عن |
|
|
|
168 |
|
00:12:39,050 --> 00:12:43,070 |
|
collagen و هو طبعا ال collagen لونه أبيض فهو اللي |
|
|
|
169 |
|
00:12:43,070 --> 00:12:48,430 |
|
بيعطي اللون ل .. ال .. اللون الأبيض ل ال .. ال |
|
|

170 |
|
00:12:48,430 --> 00:12:51,790 |
|
fibers هادي أو لال ligament لأنه إذا لاحظنا إحنا |
|
|
|
171 |
|
00:12:51,790 --> 00:12:54,870 |
|
اللي بطلع على ال ligamentبيكون لونه أبيض غير عن ال |
|
|
|
172 |
|
00:12:54,870 --> 00:12:58,230 |
|
muscle ال muscle بيكون لونه أحمر لأنه هو ال muscle |
|
|
|
173 |
|
00:12:58,230 --> 00:13:05,730 |
|
مليانة blood vessels لكن هذه ال .. ال .. ال fibers |
|
|
|
174 |
|
00:13:05,730 --> 00:13:10,130 |
|
أقل طبعا ل blood vessels طبعا كنتش manufactured by |
|
|
|
175 |
|
00:13:10,130 --> 00:13:15,170 |
|
ال fibroblasts وهي قلنا الخلايا البناء اللي موجودة |
|
|
|
176 |
|
00:13:15,170 --> 00:13:21,640 |
|
أو ال immatures اللي بتعمل عملية البناءكمان الـ |
|
|
|
177 |
|
00:13:21,640 --> 00:13:26,980 |
|
Collagen matures كل ما صار mature أكرر فيه an |
|
|
|
178 |
|
00:13:26,980 --> 00:13:31,640 |
|
increase of both density and stability وكمان اللي |
|
|
|
179 |
|
00:13:31,640 --> 00:13:35,780 |
|
بتساعد على الربط which result in increased tissue |
|
|
|
180 |
|
00:13:35,780 --> 00:13:39,580 |
|
strength and stiffness many type of collagen have |
|
|
|
181 |
|
00:13:39,580 --> 00:13:43,340 |
|
been identified هم لاقوا انه فيه عند 19 يعني 19 |
|
|
|
182 |
|
00:13:43,340 --> 00:13:49,040 |
|
different collagen type موجودة في ال tendon و ال |
|
|
|
183 |
|
00:13:49,040 --> 00:13:49,680 |
|
ligaments |
|
|
|
184 |
|
00:13:52,700 --> 00:13:55,580 |
|
طبعا هنا tendon و ال ligament بتكون primarily من |
|
|
|
185 |
|
00:13:55,580 --> 00:14:00,720 |
|
type 1 او اقريبا 70% dry wet with a small amount |
|
|
|
186 |
|
00:14:00,720 --> 00:14:04,920 |
|
of type 3 يعني تلاتة في المية تقريبا من تلاتة |
|
|
|
187 |
|
00:14:04,920 --> 00:14:08,680 |
|
العشرة في المية and a trace يعني .. يعني نسبة |
|
|
|
188 |
|
00:14:08,680 --> 00:14:18,600 |
|
ضعيفة من ال type خمسة و عشرة و واحد عاش و هك |
|
|
|
189 |
|
00:14:18,600 --> 00:14:23,670 |
|
تقريبا أربعة عاشHowever, the proportion of |
|
|
|
190 |
|
00:14:23,670 --> 00:14:26,750 |
|
collagen type present various amounts specific |
|
|
|
191 |
|
00:14:26,750 --> 00:14:32,130 |
|
tendon and طبعا يعني كميات ال .. ال .. نسب لل .. |

ال collagen اللي موجودة في ال tendon و ال ligament |
|
|
|
193 |
|
00:14:35,770 --> 00:14:39,990 |
|
بتختلف حسب ال ligament طبعا هنا example ال tendon |
|
|
|
194 |
|
00:14:39,990 --> 00:14:43,770 |
|
بتقريبا بيكون فيه انه type 3 collagen و ال |
|
|
|
195 |
|
00:14:43,770 --> 00:14:49,910 |
|
ligament فيه أكتر نسبة من ال type 3 collagen طيب |
|
|
|
196 |
|
00:14:51,980 --> 00:14:55,980 |
|
هلأ بالنسبة للـ Elastin الـ Elastin هي المادة |
|
|
|
197 |
|
00:14:55,980 --> 00:15:02,180 |
|
بتكون أقل موجودة في ال .. موجودة في نسب أقل في ال |

.. في ال ligament في ال fibers composition of the |
|
|
|
199 |
|
00:15:05,660 --> 00:15:09,300 |
|
ligament التندن في نسبة قليلة من ال elastin عشانك |
|
|
|
200 |
|
00:15:09,300 --> 00:15:13,940 |
|
احنا ب .. يعني يكون التندن في less elasticity طبعا |
|
|
|
201 |
|
00:15:13,940 --> 00:15:16,840 |
|
ال proportion أو النسبة بين ال elastin و ال |
|
|
|
202 |
|
00:15:16,840 --> 00:15:21,130 |
|
collagen بتختلف حسبالـ ligament و مكانه و موقعه |
|
|
|
203 |
|
00:15:21,130 --> 00:15:24,170 |
|
موضوع في الأضره ولا في ال lower limb big joint |
|
|
|
204 |
|
00:15:24,170 --> 00:15:28,370 |
|
small joint حسب ال joint اللي بيكون موجود فيه in |
|
|
|
205 |
|
00:15:28,370 --> 00:15:32,450 |
|
most ligaments of the joints as in tendon ال |
|
|
|
206 |
|
00:15:32,450 --> 00:15:37,050 |
|
collagen present in much high proportion than |
|
|
|
207 |
|
00:15:37,050 --> 00:15:40,830 |
|
elastin لإن المكوّن الأكبر بيكون collagen سواء في |
|
|
|
208 |
|
00:15:40,830 --> 00:15:44,110 |
|
ال ligament أو في ال tendon |
|
|
|
209 |
|
00:15:48,360 --> 00:15:52,020 |
|
أما الـ Ground Substance فهي عبارة عن non-fibrous |
|
|
|
210 |
|
00:15:52,020 --> 00:15:56,620 |
|
part of extracellular material composed of |
|
|
|
211 |
|
00:15:56,620 --> 00:16:01,480 |
|
glycoprotein وبروتيوглиكان وكمان water إيش وظيفتها |
|
|
|
212 |
|
00:16:01,480 --> 00:16:05,620 |
|
تعمل adhesions of cells to the fibers and other |
|
|
|
213 |
|
00:16:05,620 --> 00:16:10,860 |
|
extracellular matter هي زي ال glue زي سمل اللي |
|
|
|
214 |
|
00:16:10,860 --> 00:16:15,760 |
|
بيجمع هذه الأشياء وبيربطها في بعضها |
|
|
|
215 |
|
00:16:20,470 --> 00:16:26,830 |
|
طبعا الـ protein glucan بيتمثل تقريبا أقل من 1% من |
|
|
|
216 |
|
00:16:26,830 --> 00:16:32,070 |
|
ال tendon total dry weight لكن هم ال key role |
|
|
|
217 |
|
00:16:32,070 --> 00:16:38,590 |
|
عندهم يعني بيشكلوا key role في ال ligament و ال |
|
|
|
218 |
|
00:16:38,590 --> 00:16:43,610 |
|
tendon function لإن هم بيحافظوا على ترابط الأنسجة |
|
|
|
219 |
|
00:16:43,610 --> 00:16:48,620 |
|
هذه مع بعضهاأما البروتيو .. البروتيو كليرانس also |
|
|
|
220 |
|
00:16:48,620 --> 00:16:51,620 |
|
help in regulate .. maintain the structural |
|
|
|
221 |
|
00:16:51,620 --> 00:16:54,760 |
|
organization of the tissue by providing بعض ال |
|
|
|
222 |
|
00:16:54,760 --> 00:16:59,500 |
|
support و بيعمل مساحة spacing بين ال cells و ال |
|
|
|
223 |
|
00:16:59,500 --> 00:17:05,190 |
|
fibers of connective tissueالـ vascular supply of |
|
|
|
224 |
|
00:17:05,190 --> 00:17:07,950 |
|
the tendon and ligament طبعا ال tendon و ال |
|
|
|
225 |
|
00:17:07,950 --> 00:17:11,730 |
|
ligament اللي فيهم less vascularization than ال |
|
|
|
226 |
|
00:17:11,730 --> 00:17:14,530 |
|
muscle ال muscle اللي إحنا بنعرف إنها فيها highly |
|
|
|
227 |
|
00:17:14,530 --> 00:17:17,510 |
|
vascularized ده اللي بيعطيها الشكل أو اللون الوردي |
|
|
|
228 |
|
00:17:17,510 --> 00:17:20,010 |
|
أو الأحمر أما ال tendon لأنه مافيش فيه |
|
|
|
229 |
|
00:17:20,010 --> 00:17:23,690 |
|
vascularization ف .. و بياخد طابع إن هو موجود فيه |
|
|
|
230 |
|
00:17:23,690 --> 00:17:27,530 |
|
كمية collagen أكتر فبيكون لونه مائل على البياد |
|
|
|
231 |
|
00:17:27,530 --> 00:17:31,310 |
|
أكترالـ blood vessels in the tendons represent |
|
|
|
232 |
|
00:17:31,310 --> 00:17:38,530 |
|
only about 1% ل2% of the extracellular matrix, |
|
|
|
233 |
|
00:17:39,690 --> 00:17:42,130 |
|
thus appear white compared to the highly |
|
|
|
234 |
|
00:17:42,130 --> 00:17:45,410 |
|
musculated color of the muscle from which they |
|
|
|
235 |
|
00:17:45,410 --> 00:17:51,030 |
|
originate الطيب التندن receive their blood supply |
|
|
|
236 |
|
00:17:51,030 --> 00:17:55,800 |
|
directly من وين بياخد من البريميديااللي هو الغشاء |
|
|
|
237 |
|
00:17:55,800 --> 00:18:01,820 |
|
المحيط بالعضلة أو ال outer part |

of the muscle المحيط، الغشاء المحيط بالعضلة وكمان |
|
|
|
239 |
|
00:18:08,080 --> 00:18:13,340 |
|
من الberucin insertion وقتش ال tendon بيمسك بال |
|
|
|
240 |
|
00:18:13,340 --> 00:18:18,080 |
|
bone بنسمي berucin insertion بياخد التغذية وكمان |
